In addition to mobile networks, smartphones also have other connections that users do not always need to maintain.
Connections such as Wi-Fi, NFC or Bluetooth are quite common on smartphones to help users connect to Wi-Fi networks, make mobile payments or connect to wireless devices. Among these, Bluetooth is often turned on constantly, especially for those who use wireless headphones.
Bluetooth is often maintained to quickly connect to wireless headphones.
Bluetooth is often maintained to quickly connect to wireless headphones.
However, keeping this connection active can pose a potential security risk to the user's device. They can be victims of attacks and intrusions through this connection, although certain parameters must be met for an intruder to take advantage of Bluetooth vulnerabilities in the device. Let's find out clearly why we need to turn off Bluetooth completely when not in use.
Bluetooth is a very comfortable and practical type of connection, especially if the user uses the various accessories available for smartphones, such as headphones, smartwatches and fitness bands. However, Bluetooth can also suffer from security flaws and vulnerabilities - something that has happened many times, including in cases like BlueBorne, a security flaw that affected hundreds of millions of devices across the world.
Recently, authorities have warned about a Bluetooth connection-based attack called Bluesnarfing with the ability to illicit access device through Bluetooth vulnerabilities. This is why authorities recommend turning off Bluetooth connectivity if users are not using it. You should also turn off Wi-Fi when leaving home and only connect to trusted networks.
Users should go to the phone's connection settings to turn off Bluetooth completely when not in use.

However, despite the risks, to exploit the Bluetooth vulnerability, attackers and cybercriminals will need to meet certain conditions, even if manufacturers do not regularly update the software. software for Bluetooth. These include conditions:
- First and most obvious, the victim's device must have some Bluetooth-related security vulnerability. Not all smartphones are vulnerable just because they have an active Bluetooth connection.

- Second: The attacker must always be near the victim to perform Bluetooth intrusion. Besides, even when taking advantage of crowds, the signal can be disturbed because there are too many people.
However, even if the risk is low, this does not mean that users cannot become victims of a Bluetooth attack or intrusion. So a basic rule should be followed: If we don't use it, it's better to turn it off.
